Abstract (en)
[origin: WO2010076081A2] The invention relates to an electric machine, particularly a transversal flux machine, comprising a rotor (1) designed as outer rotor (2) or inner rotor (57), comprising at least one reflux ring (7) having a longitudinal axis (27, 39, 52), permanent magnets (3, 31, 44, 58) having alternating magnetic polarity (14, 32) being disposed in an angular offset manner on said reflux ring. According to the invention, the reflux ring (7) comprises at least two axially adjacently joined reflux partial rings (5, 6, 28, 29, 35, 43, 50, 51, 60, 61) and the permanent magnets (3, 31, 44, 58) are located in the gaps (17) between the permanent magnets (3, 31, 44, 58) of the other reflux partial ring (5, 6, 28, 29, 35, 43, 50, 51, 60, 61) when joining the two reflux partial rings (5, 6, 28, 29, 35, 43, 50, 51, 60, 61). The invention further relates to a method for producing an electric machine.
